Hi, I found a tablet in my house and I don't know what it is. I have looked on drug sites but had no joy. It is in an orange blister packet but the pill is actually white, quite small and round. I can read a few letters on packet but it has been trimmed so can't see whole name. I can just about see thas or thaso. It has no imprint on the actual pill as far as I can see. Does anyone have any idea please?
